SPECIFICATION forming part of Letters Patent No. 646,158, dated March27, 1900. Application filed July 7, 1899. Serial ITo. 723,070. (Nomodel.)

To ctZZ whom it may concern.-

Be it known that I, LOUIS RABORN, acitizen of the United States,residing at Whitney,

The leading thought of the present inven tion is the provision of acompress dispensing with the useof a core around which the lintcotton inthe form of a bat from a condenser I is rolled into convolutions for theformation of a cylindrical bale.

other, so that the rolls will exert pressure'on the embryo bale and willalso serve torotate it in order to coil the bat thereon.

A further object of the invention is to provide means for exerting thepressure on the rolls to make them compress the cotton-bat around theembryo bale, and such pressureexerting appliances are disposed foroperation conjointly with the rotary motion given to the rolls andWithout being affected by the separation of the rolls during theformation of the bale.

Afurther object of the inventionis to provide an improved pressureproducing appliance arranged to multiply the effect of counterweightsand to exert pressure uniformly on the movable rolls of the set ofcoacting rolls, and with such pressure-producing appliance is combined ameans for conveniently separating the movable rolls relative one to theother and to the non-slidable rolls, so as to provide for ejectment ofthe bale.

A further object of the invention is to provide means which prevent theheads of the embryo bale from riding against the pressframe, suchlimiting-plates being free to rotatc with the bale and to travel in thepresstion, I have illustrated the preferred embodiment thereof in theaccompanying drawings, forming a part of this specification and inWhich.

Figure 1 is side elevation ofa roller cotton-com press constructed inaccordanoewith the present invention, illustrating more particularly thep'ressure-exertin g appliances for the s'lidable working rolls andthe'driving mechanism by which each roll of the series A further objectof the invention is to provide means for the separation of the rolls tomake them yield-able to the enlargement of the embryo bale without,however, disturbing v the equidistant relation of the rolls one to the'of working rolls may be positively rotated on its axis. Fig. 2 is asectional plan view of the compress shown by Fig. 1. grammatic sectionalelevation illustrating the relation of the working rolls at thebeginning of the operation of forming a bale, the plane of the sectionbeing indicated on the dotted line 3 3 of Fig. 2. Fig. 4 is a detailedsection, taken transversely in a vertical plane,through the press-frameand illustrating a part of said frame and the limiting end plates forthe bale, the latter being shown in a conventional manner. Fig. 5 is adetailed perspective view of one of the end disks for the bale, showingthe stub-axle and bearing-ball for said disk. v

The same numerals of reference are used to indicate like andcorresponding parts in each of the several figures of the drawings.

In carrying this invention into practice I employ a framework 10 ofanysuitable character to support the working rolls, the pressure devicestherefor, and the driving mechanism by which the rolls are rotatedpositively, and it will therefore be understood that I do not limitmyself to the style of framing illustrated by Figs. 1 and 2 of thedrawings. This framing supports a feed-table 11,

(shown by Fig. 3 as arranged in a substantially-horizontal position,)and on this table the lint-cotton from a condenser or other suitablesource of supply is deposited for deliv- Figr 3 is a'diacry to the setof coacting rolls, which constitute the lcadin g feature of the compressmechanism forming the subject-matter of this application.

According to my invention it is necessary to employ a set of threecoacting working rolls,which are arranged for their axes to occupypositions equivalent to the angles or corners of a triangle and one ofthese rolls has its shaft mounted in fixed bearings for rotation on astationary axis, while the other rolls are mounted for slidable travelon divergent or convergent lines with relation to the axis of thenon-traveling roll, all of the rolls being positively driven and each ofthe slidable rolls being held by pressure devices in yieldable relationto the non-traveling roll. The working rolls are indicated by thenumerals 12 13 14, and they are disposed contiguous to the delivery edgeof the feed-table 11. The roll 12 has its shaft 12 journaled instationary bearings in the framing in a position for its upper surfaceto lie in substantially the horizontal plane of the feedtable 11, sothat the lint-cotton will pass from the table directly upon the nontraveling roll 12.

The rolls 13 let are disposed in the same vertical plane with relationone to the other and at one side of the vertical plane of the roll 12,although this particular arrangement of the two slidable rolls is notstrictly essential. The rolls 13 11 are guided or mounted for their axesto lie above and below the horizontal plane of the non-traveling roll12, respectively, and said slidable rolls are adapted to move during theformation of the bale in divergent lines away from each other and fromthe roll 12. The upper roll 13 has its shaft 15 arranged to travelfreely in the upwardlyinclined guideway 10', and in like manner thelower roll It has its shaft 17 mounted to travel freely in adownwardly-inclined guideway 18. These guideways are shown by Figs. 1and 3 as being formed by slots in the framing 10; but theparticularconstruction of these guideways is not material. Saidguideways 16 18 diverge from the axis of the non-traveling roll 12.

It is important in a press employing a pair of yieldable or travelingrolls adapted to recede from a stationary or nontraveling roll to makeprovision for giving uniform movement or play to the traveling rolls andalso to exertpressure on said traveling rolls for holding them in properrelation to the nontraveling roll, so as to compress the bat on theembryo bale during its formation. I obtain the object of equalizing thetravel of the slidable rolls by pairs of links 19 20 and by a commonequalizing-bar 21, the latter being guided to travel in the horizontalplane of the non-traveling roll 12. A pair of equalizinglinks 19 20 isdisposed at each end of the rolls 13 14;, the links 19 being connectedto the shaft 15 of the roll 13, while the links 20 are loosely connectedto the ends of the shaft 17,

on which the roll 14 is mounted. The links constituting each pairconverge from the shafts of the rolls toward the equalizing-bar 21, andsaid links of each pair have common connection loosely with said bar.This equalizing-bar 21 is free to travel in a horizontal guideway 22,which is arranged in a horizontal plane of the shaft12, that carries thenontraveling roll 12.

The means which I prefer to employ for exerting pressure uniformly onthe traveling rolls 13 ll of the set of coacting working rolls consistsof counterweighted levers arranged in pairs on opposite sides of thepress-frame andhaving independent linked connection with the shafts ofsaid slidable rolls. A lever 23 is fulcrumed at 22 contiguous to oneguideway 16 or 18 for each slidable roll, and this lever is connectedoperatively with a roll-shaft by an intermediate link 25, said linkhaving loose connections with roll-shaft and a pivotal connection at 26to the lever at a point intermediate the length of thelatter. The levers23 are arranged in pairs on opposite sides of the press-frame, each pairof levers being inclined to cross one another, as clearly shown by Fig.1, the fulcra 24 of said levers being arranged opposite to the divergingguideways. Guide-sheaves 27 are journaled on the press-frame at suitablepoints near the levers 23, and over these guide-sheaves pass the cables28, which are fastened to the free ends of levers 23. Said cables passdownwardly through the press-frame and are attached to a-counterweight29. As shown by Fig. 1, a single counterweight has both of the cables 28fastened thereto for the purpose of drawing the levers of a pair towardeach other and, through the links 25, pressing the slidable rolls 13 1ttoward the non-slidable roll. It is to be understood that a pair of thelevers or links and a single counterweight are employed on each side ofthe press, as represented generally by Fig. 2 of the drawings. I havearranged the levers23 for the fulcra thereof to lie equidistant from theaxes of the slidable rolls 13 14, and by employing a counterweight whichis common to the levers of each pair the pressure-producing mechanism ismade to apply pressure uniformly to the slidable rolls of the coactingworking rolls.

It is desirable in a three-roller cotton-compress to provide a mechanismby which the rolls may be conveniently separated by manual adjustmentafter the bale has attained the desired diameter in order that the balemay be ejected or discharged from the working rolls. I attain thisobject by the provision of a hand-lever 30, which is fulcrn med at oneend to the press-frame, on the outside thereof. To this hand-lever isconnected one end of a pitman 31, the opposite end of which is pivotallyconnected to a cross-rod 32, the latter being arranged in a horizontalposition across the press-frame and fitted to slide freely in horizontalslots or guideways 32. Diverging links are connected in pairs toopposite ends IIO of the slidable cross-rod 32, and each pair of thelinks on one side of the press is pivotally connected with the freeends'of the levers 23, the pivotal connection of the links 33 to thelevers 23 being adjacent to the points of adjustment of the cables 28 tosaid lovers. The handle of the lever 30 is mounted to traverse a notchedsegment 34, which is fixed on the side of the press-frame in the path ofsaid lever; but a part of this segment has a smooth pressure devicestoward the non-traveling roll. The pressure devices associatedindividually with the slidable rolls apply the pressure theretosubstantially in the plane of travel of said rolls as they diverge orrecede from the roll 12 during the formation of'the bale, whereas theequalizing-bar 21 and the pairs of links tend to draw the rolls 13 14toward each other, thus maintaining-the trav eling rolls in properrelation one to the other and to the roll 12.

In connection with the setof rolls arranged and operating in the mannerdescribed I employ a driving mechanism for positively rotating each rollon its axis, and while this driving mechanism may be of any suitablecharacter I have iliustrated one adaptation thereof in Figs. 1 and 2 ofthe drawings.

The means for rotating the rolls is in the form of speed-reducinggearing which embodies as one element thereof aprime shaft 41, journaledin suitable bearings of the framing 10 and provided with suitablepulleys, one pair of which pulleys is indicated at 42 for 00- actingwith the counter-shaft 43, that is j ournaled in the framing in parallelrelation to said prime shaft, the latter being driven in any suitableway from a line-shaft or a motoras, for example, by a pulley 41. (SeeFig. 2.) The counter-shaft 43 has double pulleys 44 45, which pulleysare of different diameters, and the large pulleys 44 are con-.

nected by-belts 46 with the small pulleys 42 on the prime shaft. Theshaft for driving the compress-rolls is indicated at 47 as beingjournaled in bearin gs on the frame in parallel relation to thecounter-shaft 43, and this driving-shaft has a series of pulleysindicated at 48 49 50, the pulleys 48 being operatively connected by thebelts 51 to the pulleys 45 on the countershaft, whereby this countershaft transmits the motion of the prime shaft 41 to the driving-shaft47, and the speed is reduced in order to impart slow speed to thedrivingshaft 47. This driving-shaft is connected in 'leys 55 on saidshaft of the roll 14.

64am s dividually with the shafts of the three work ing rolls 12 13 14,and as the shaft 47 and the shaft 12 of the non-traveling roll 12 are infixed relation one to the other I find it desirable to employsprocket-gearing, as 52, (see Fig. 2,) for operatively connecting theshaft of the non-traveling roll with the driving-shaft, thus minimizinglost motion between the roll 12 and the shaft 47. The shaft 15 of theupper slidable rollis equipped with a belt-pulley 54 at each end, andthe pulleys 49 54 are connected operatively by the endless belts 53. Inlike manner the shaft 16 of thelower slidable roll 14 is provided withbelt-pulleys 55, and endless belts 56 are employed to connect thepulleys 50 on the driving-shaft with the pul- It will thusbe seen thatthe slidable rolls are connected individually by power-transmittingappliances to the driving-shaft, from which is propelled thenon-slidable roll 12, and as the slidable rolls are adapted to recedefrom v the non-traveling roll it is necessary to provide a permanentallowance of abundant slack in the belts which connect the shafts of.the rolls 13 14 with the driving-shaft 47 In view of this allowance ofslack in the belts 53 55 to permit the rolls 13 14 to recede from theroll 12 and to secure sufficient friction on the belts for thetransmission of motion to saidslidable rolls to eifect their positiverotation the driving mechanism is equipped with belt-tightenerdevicesdisposed in operative relation to the belts 53 55. Thesetightener devices are shown by Fig. 1 as embodied in the form ofspring-actuated tension-rollers 57 58, arranged to individually rideupon the belts 53 55, and said tension-rollers are slidably confined insuitable guides 59 on the frame.

.To properly direct the lint-cotton to the working rolls, as well as tocondense the cotton as it passes from the feed-table, I employ thecondensing-roller 60, which is mounted directly over the roll 12 in thevertical plane of the shaft thereof This condensing-roller is mountedidly in suitable bearings on the frame,and, if desired, saidcondensing-roller may be held yieldably in relation to the roll 12 byspring-actuated or weighted bearings. As these are well-known devices inpress construction, I have not considered it necessary .to illustratethe same.

During the enlargement of the bale the lower roll 14 travels away fromthe roll 12, and hence a gap or space exists between said rolls, whichwould have a tendency for the lint-cotton to drop away from the rolls.To overcome this objection, I employ a detaining-roller 61, which isdisposed in the vertical plane between the axes of the rolls 13 14 andthe roll 12. This detaining-roller is adapted to yield to theenlargement of the embryo bale during its formation, and to properlykeep the detaining-roller in operative relation to the bale said rolleris mounted to travel in guides 62 on the frame. A suitable tension orpressure device 63 acts against the detaining-roller to hold it up tothe bale, and this tension device yields or gives for thedetaining-roller to descend as the bale enlarges.

lVhen the compression-rolls are closed to'-' gether, as shown by Fig. 3,the bat-roller 61 is held in a position against the lower side of therolls 12 14; but as the roll 14, with the roll 13, moves away from theroll 12 on theenlargement of the bale, this bat-roller 61 is movedautomatically into the space between the two rolls 12 14, so as to serveas abarrier to the bat and prevent it from dropping. This isaccomplished by mounting the batroller to slide freely in the guides 62of the frame (see dotted lines in Fig. 3) and by the use of the springs63, (see Fig. 1,) which act to move the bat-roller in an upwarddirection on the separation of said rolls 12 14.

To prevent the ends of the embryo bale from riding against the sides ofthe pressframe and to minimize the friction between the ends of theembryo bale and the pressframe, I have provided the disks 64 65 onopposite sides of the bale, forming a space or chamber between the setof triangularly-arranged coacting working rolls 12 13 14. Each end disk64 65 is equalin diameter to the bale when complete, and said disks 6465 are fitted or confined loosely in horizontal recesses 66, which areproduced in the opposing faces of the sides of the press-frame, asclearly shown by Fig. 4. Said disks are free to travel lengthwise in thehorizontal recesses on the enlargement of the bale, and each disk isprovided with a stub-axle 67, said axle extending laterally from theouter face of the disk and fitted slidably in a horizontal slot 68,which is formed in the press-frame. The slot 68 in each side of thepress-frame is arranged centrally and parallel to the horizontal recess66, said slot and recess communicating directly, as shown by Fig. 4. Tothe outside of the press-frame is secured in a suitable way a horizontalmetallic bearing-plate 69, which covers the horizontalslot 68, andagainst this bearing-plate rides a bearing-ball 70, the latter beingconfined to the recess 71, which is produced in the end of the stub-axle67 on one of the limiting orend disks 640165. The horizontal recess 66and the slot 68 incommunication with said recess liein the horizontalplane of the shaft 12, that supportsa nonslidable working roll 12, andthe end plates 64 65 are adapted to travel in the recess and the slotsin a plane coincident with the axis of the non-slidable roll. At thesame time the end disks 64 65 are free to rotate with the embryo baleduring the process of winding the cotton-bat into the convolute orspiral form to produce a cylindrical bale, the rotation of the end disks64 65 being due to friction between the ends of the bale and said disks.As the disks 64 65 are supported by stub-axles, which have ball-bearingengagement with metallic bearing-plates on the press-frame, it isevident that the friction beequalizing-bar 21.

tween the disks and the press-frame is mini-' mized.

The employment of the bearing-plates 69 limits the displacement of theend disks with relation to the ends of the bale, and by fitting saiddisks and the stub-axles thereof in the recesses and the slots of thepress-frame the disks are confined in operative relation at all times tothe bale during the process of its formation.

The operation is as follows 2' The bat of lint cotton from the condenseror other source of supply is fed to the table 11, and the pressuredevices force the traveling working rolls 13 14 into contact with theroll 12 and with each other, as clearly shown by Fig. 3, the disks 64 65occupying an axial relation to the space or chamber between thetriangularly-disposed rolls. The driving-gearing positively rotates allthe rolls on their axes and the lint-cotton is fed to the working rollsby passing between the condensing-roll 60 and the working roll 12. Byreference to Fig. 3 it will be noted that my compression mechanismdispenses with the employment of a core, and the rolls 12 13 14 providea substantially-triangular space between their meeting and opposingsurfaces. At the beginning of the operation of feeding lint-cotton tothe rolls the bat passes over the surface of the roll 12 andlodgesuponthe upper surface of the roll 14, and from thence the bat is lifted bythe rotary action of the roll 14 into contact with the lower surface ofthe roll 13, the last-named roll serving to deflect the cotton-battoward the opposing surface of the roll 12. All of the rolls beingpositively driven, the cotton-bat is caused to pursue a course similarto a convolute or spiral, and the bat is thus coiled or rolled uponitself to produce a cylindrical bale. The series oftriangularly-arranged working rolls support the embryo bale and rotateit, so as to make the action of forming the bale progressive andcontinuous. As the ICC diameter of the embryo bale increases theslidable rolls 13 14 recede from the roll 12; but they are normally heldin contact with the bale for properly supporting the latter and forcompressing the cotton-bat thereon by the action of their pressuredevices, the travel of the slidable rolls being uniform under thelimiting action of the links 19 20, which have common connection withthe The disks 64 65 slide in horizontal paths on the enlargement of theembryo bale, due to the frictional engagement between said disks and theends of the bale. The lint-cotton is compacted or condensed by theroller 60 as it passes from the feed-table to the working rolls, andduring the enlargement of the bale the detaining-roller 61 prevents thecotton-bat from dropping or falling through the gap or space exposed bythe separation of the roll 14 with respect to the roll 12. The bale whencompleted may be discharged from the roller-compress by shifting thelever 30 toward the notched end of the segment and drawing on the links33 to move the levers 23 in a direction to adjust the rolls 13 14 awayfrom the cylindrical bale. This adjustment of the lever 30 elevates thecounterweight 29, and as the lever is held fast by .its engagement withthe segment it is evident that the bale may be tied or bound previous toits discharge from the press. The lever may be released from the notchedsegment forthe counterweight to return the slidable rolls to theirinitial positions and in engagement with the non-slidable roll 12,thereby placing the compress in a condition to renew the operation ofmaking a cylindrical bale.

Changes may be made in the form and proportion of some of the partswhile their essential features are retained andthe spirit of theinvention embodied. Hence I do not desire to be limited to the preciseform of all the parts as shown, reserving the right to vary therefrom.
